I am attempting to dual boot windows and ubuntu 18 LTS (as of today 12.14.19).

I have formatted my usb drive with etcher and installed the ubuntu iso... this worked fine. Then I went into Windows 10 Disk Manager and shrunk my C drive and allotted 200GB of "Free Space" for ubuntu to go into. I turned off Safe Mode in Bios. I plug in my usb, restart, press f12 to see my boot menu. I boot into my usb/ubuntu and ubuntu boots up fine through the grub loader.

Once I am in Ubuntu I open the terminal and type 'gparted', when the GUI opens it only shows one partition which is dev/sda and is only the 30GB's of my usb stick. I do not see the 200GB I allotted in Windows 10 Disk Manager. So even when I try to partition the space manually I only have 30GB's to work with. Why doesn't ubuntu recognize my 200GB of space?

FYI in BIOS I have SATA not AHCI checked

From my experience, do NOT create the dual boot with Windows 10 and Ubuntu. When Windows 10 gets an Update, it will change and mess up the UEFI dual boot system.

Best way to have both is two different hard drives, hooked up with a switcher. That's what I am doing.

It does save your both of your OS and save your time to Reinstall everything again.
